DETAILED DESCRIPTION OF THE EMBODIMENTS

The concept, specific structures, and produced technical effects of thedisclosure are clearly and thoroughly described below with reference tothe embodiments and the accompanying drawings for thorough understandingof the objectives, features, and effects of the disclosure.

Obviously, the described embodiments are merely some embodiments of thedisclosure, rather than all the embodiments of the disclosure. Based onthe embodiments of the disclosure, all other embodiments derived by aperson skilled in the art without any creative efforts shall fall withinthe protection scope of the disclosure.

In addition, all connection relationships involved herein do not merelymean that members are directly connected, but instead, a connectionaccessory may be added or reduced according to specific implementationcases to form a preferred connection structure. All technical featuresin the disclosure can be combined with each other without causing anycontradictions.

As shown in FIG. 1, a storage jar in this embodiment includes a jar body10 and a lid body 20.

The jar body 10 is provided with an accommodating cavity foraccommodating stored substances. The accommodating cavity is provided,at a top of the cavity, with an opening for filling or taking out thestored substances.

The lid body 20 is arranged at the top of the jar body 10 and may coverthe accommodating cavity, so that substances in the accommodating cavityare separated from outside.

As shown in FIG. 1, the jar body 10 has a cross section of approximatelyrectangular shape. Certainly, circular, elliptical, polygonal designs,among other designs, may all be possible.

As shown in FIG. 1, FIG. 2, and FIG. 4, in some embodiments, a firstgroove 12 is provided in a side wall of the jar body 10, and the firstgroove 12 is provided in an outer surface of the jar body 10. Therefore,the first groove 12 increases the strength of the jar body 10, and thejar body 10 is less susceptible to deformation, so that the jar body 10can be vertically placed.

The first groove 12 may have a triangle shape as shown in the figures ormay be of another design, which is set according to requirements.

For convenient manufacturing, the first groove 12 may be communicatedwith the bottom wall of the jar body 10. In this way, the first groove12 can be directly demolded without having to arranging a complexstructure such as a wedge.

To make it convenient to move the storage jar, the cross sectional areaof the first groove 12 may increase in a direction towards the bottomwall of the jar body 10.

The increase of cross sectional area of the first groove 12 in thedirection towards the bottom wall of the jar body 10, on one hand, isconvenient to demold the jar body 10, and on the other hand, facilitatesa finger to extend into the first groove 12 to lift the storage jar, andthe finger tends to move towards the top of the first groove 12.However, in this case, the cross sectional area of the first groove 12gradually decreases, and the jar body 10 does not fall off easily from ahand, so that it is convenient to move the storage jar with both hands.

Furthermore, when a protrusion is formed in the accommodating cavity toform the first groove 12 in the jar body 10, the cross sectional areacorresponding to the protrusion decreases in the direction towards thetop of the jar body 10, so that substances are conveniently poured fromthe accommodating cavity.

Certainly, different positions of the first groove 12 may be heldaccording to the size of a hand to satisfy an actual requirement.

To make it convenient to hold the jar body 10, the first groove 12 maybe provided in the side wall of the jar body 10 in the thicknessdirection. People tend to hold the jar body 10 in the thicknessdirection to move the storage jar, and therefore, the provision of thefirst groove 12 in the side wall of the jar body 10 in the thicknessdirection makes it very convenient to put a finger in the first groove12.

Certainly, there may be a plurality of first grooves 12 distributed ontwo opposite sides of the jar body 10.

As shown in FIG. 1, FIG. 2, and FIG. 4, in some embodiments, the jarbody 10 is provided with an end surface abutting the lid body 20, afirst turnup 11 is provided at an edge of the end surface, and the lidbody 20 is accommodated within an inner side of the first turnup 11.

On one hand, the first turnup 11 expands the sectional profile of thejar body 10 to facilitate the entry of the stored substances into theaccommodating cavity without scattering and leakage. On the other hand,the first turnup 11 enables an inner side of the jar body 10 to bearranged in a step form, and gradually becomes smaller from the firstturnup 11 to the bottom wall of the jar body 10, so that the jar body 10may be manufactured using a process other than blow molding. Inaddition, the jar body 10 has uniform wall thickness, high quality, andlow costs. Furthermore, the first turnup 11 does not impede thedischarge of substances in the accommodating cavity during being poured,so that the accommodating cavity can be completely emptied.

The jar body 10 may be made of a transparent plastic material. Throughthe transparent jar body 10, the number and quality of substances in thejar body 10 can be conveniently observed, so that it is convenient toestimate how long the substances can last and make a preparation inadvance.

As shown in FIG. 1, FIG. 2, and FIG. 3, in some embodiments, the lidbody 20 may be provided with a second turnup 22 covering an end portionof the first turnup 11. The second turnup 22 covers the end portion ofthe first turnup 11, that is, covers the top of the first turnup 11, soas to prevent dust or the like from entering the accommodating cavitythrough a gap between the lid body 20 and the first turnup 11, therebyprotecting stored substances from pollution.

In addition, the lid body 20 may further be taken out from a spacedefined by the first turnup 11 by tilting the second turnup 22, so thatthe lid body 20 is conveniently opened and closed.

In some embodiments, the lid body 20 may be provided with a raisedportion 21 which is arranged on a side of the lid body 20 facing awayfrom the jar body 10.

The raised portion 21 is raised towards the side of the lid body 20facing away from the jar body 10. Therefore, the raised portion 21 mayserve to form a portion for a hand to pick up and put down the lid body20 conveniently. In addition, the raised portion 21 may be designed as athin shell to increase the storage space of the storage jar. Certainly,the raised portion 21 may also help to increase the strength of the lidbody 20.

In some embodiments, the lid body 20 may be provided with a secondannular groove 23, and the raised portion 21 is arranged on an innerside of the second annular groove 23. The second annular groove 23 canincrease the strength of an edge of the raised portion 21, thus reducingthe risk of breakage of the edge of the raised portion 21 duringdisassembling.

The second annular groove 23 and the raised portion 21 may be arrangedat the same side of the lid body 20 or at different sides. That is, oneof the second annular groove 23 and the raised portion 21 is located ata side of the lid body 20 facing the jar body 10, and the other islocated at the other side of the lid body 20 facing away from the jarbody 10.

The second annular groove 23 may be a single groove or may be aplurality of grooves arranged in a circle surrounding the raised portion21 to produce the same effect.

As shown in FIG. 1 and FIG. 2, in some embodiments, a buckling structure30 is provided between the lid body 20 and the jar body 10 fordetachably connecting the jar body 10 to the lid body 20.

Specifically, the buckling structure 30 includes a buckling arm 31 and abuckling portion 32 engaged with each other. The buckling arm 31 isprovided with a hand-held portion 33. The hand-held portion 33 may be ahalf-moon arc-shaped plate as shown in the figures. Certainly, thehand-held portion 33 may have another shape provided that aforce-applying point for a hand is provided.

When the lid body 20 needs to be removed, the hand-held portion ispulled with a finger 33 to further disengage the buckling arm 31 fromthe buckling portion 32 to open the buckling structure 30.

When the lid body 20 needs to be assembled, the hand-held portion 33 ispulled in the opposite direction to bring the buckling arm 31 toapproach the buckling portion 32, so as to buckle the buckling structure30 to fixedly connect the lid body 20 to the jar body 10.

To achieve more reliable buckling, the buckling arm 31 may be providedwith a first hole portion 35 for accommodating the buckling portion 32.

Therefore, the buckling arm 31 is pulled to allow the buckling portion32 to be inserted into the first hole portion 35 so as to connect thebuckling portion 32 to the buckling arm 31 accurately and reliably, andit is convenient to visually confirm the connection.

In some embodiments, to prevent the buckling arm 31 from naturallydisengaging from the buckling portion 32, as shown in FIG. 2, thebuckling portion 32 may be provided with an anti-disengaging convexportion 34 or an anti-disengaging concave portion.

The anti-disengaging convex portion 34 or the anti-disengaging concaveportion abuts an edge of the first hole portion 35, so that on one hand,the buckling portion 32 is prevented from being disengaged from thefirst hole portion 35 under the effect of a static force, and on theother hand, the anti-disengaging convex portion 34 or theanti-disengaging concave portion may further guide the buckling portion32 to pass through the first hole portion 35, thus reducing resistanceof the buckling portion 32 passing through the first hole portion 35.

The buckling portion 32 has a plate form, and the cross sectional shapeof the buckling portion 32 is set to be curved and/or bent. By beingcurved and/or bent, it is meant that the cross section of the bucklingportion 32 may have an arc shape, a semicircular shape, a shape of adoor frame, a frame shape or a shape formed of a plurality of straightsegments connected sequentially.

Such unique design of the buckling portion 32 not only facilitates themanufacturing of the buckling portion 32, but also increases thestrength of the buckling portion 32, so that the buckling portion 32 isdurable and less susceptible to damage.

Certainly, the number of the buckling structure 30 is not limited to oneand may be increased or reduced according to the shape of the storagejar.

In the process of opening and closing the storage jar, due to the factthat it is necessary to tile the buckling arm 31 and overcome theresistance of the buckling portion 32, the buckling arm 31 are at therisk of fracturing after repeated use. In addition, when there are morebuckling structures 30, the buckling arm 31 is more likely to fracture.

As shown in FIG. 2, a limiting structure 40 is further provided betweenthe jar body 10 and the lid body 20. The limiting structure 40 and thebuckling structure 30 are arranged offset from each other in acircumferential direction of the jar body 10. The limiting structure 40and the buckling structure 30 cooperate to fix the lid body 20 to thejar body 10.

The limiting structure 40 and the buckling structure 30 being arrangedoffset from each other in the circumferential direction of the jar body10 means that the limiting structure 40 and the buckling structure 30are arranged at an outer edge of the jar body 10 and do not overlap,thus the limiting structure 40 and the buckling structure 30 can fixedlyconnect the lid body 20 to the jar body 10. Because the jar body 10 mayhave various shapes, the limiting structure 40 and the bucklingstructure 30 are not necessarily located on opposite sides of the jarbody 10.

In this embodiment, taking a line vertically passing through the centerof the opening of the accommodating cavity as an axis, the direction ofrotation around the axis on an periphery of the jar body 10 is thecircumferential direction of the jar body 10, and the direction of avertical connecting line of the periphery of the jar body 10 and theaxis is the radial direction of the jar body 10.

The limiting structure 40 and the buckling structure 30 are preferablyarranged on opposite sides of the jar body 10 in the thicknessdirection, so that the number of the limiting structures 40 and thenumber of the buckling structures 30 are reduced.

In some embodiments, the limiting structure 40 includes a limitingmember 41 and a limiting hole 42 for accommodating the limiting member41, and the limiting hole 42 has an axis extending in the radialdirection of the jar body 10.

The limiting member 41 is conveniently disengaged from the limiting hole42 to facilitate the disassembling of the storage jar. Moreover, thelimiting member 41 and the limiting hole 42 are conveniently formedduring manufacturing, and the process is simplified.

In some embodiments, the limiting member 41 has a plate form, and thelimiting hole 42 extends in the circumferential direction of the jarbody 10 and is strip-shaped.

In this way, on one hand, the strength of the limiting member 41 can beincreased to prevent the limiting member 41 from being broken, and onthe other hand, it can be ensured that the lid body 20 reliably coversthe jar body 10 without increasing the number of limiting structures 40.

In some embodiments, the limiting member 41 has a plate form, and thecross sectional shape of the limiting member 41 is set to be curvedand/or bent, which has the same advantage as described with respect tothe buckling portion 32, and it further allows for varied designs.

Certainly, the limiting structure 40 is not limited to the limitingmember 41 and the limiting hole 42 for accommodating the limiting member41. The limiting hole 42 may be alternatively a concave groove, anopening, a hook portion or the like.

By such improvement, when removing the lid body 20 from the jar body 10,the lid body 20 may be pushed towards or pushed away from one side ofthe buckling structure 30, and the buckling structure 30 is thenoperated to complete the removal, so that the required travel distanceof the buckling structure 30 can be reduced, which in turn reduces thedeformation of the buckling structure 30 and the possible damage of thestorage jar during opening and closing, and thus increases thereliability of the storage jar. In another aspect, by arrangement offewer buckling structures 30 on the storage jar, it reduces thedifficulty to manufacture the storage jar and thus reduces themanufacturing costs. In addition, the foregoing structure is alsoapplicable to containers such as food containers and crispers, whichachieves the same effect and can be widely applied and popularized.

As shown in FIG. 2 and FIG. 3, in some embodiments, the lid body 20 isprovided with a flange within the accommodating cavity, a sealing ring50 is sleeved on an outer side of the flange, and the sealing ring 50and the accommodating cavity fit together to form a seal.

Because the buckling structure 30 and the limiting structure 40 fixedlyconnect the lid body 20 to the jar body 10, the direction of a forceexperienced by the buckling structure 30 and the limiting structure 40is the direction of a connecting line between the lid body 20 and thejar body 10, and the direction of a force experienced by the sealingring 50 on the flange is perpendicular to a side wall of theaccommodating cavity. Therefore, the directions of the two forces areapproximately perpendicular. That is, the force experienced by thesealing ring 50 and the force experienced by the buckling structure 30and the limiting structure 40 affect each other slightly or do notaffect each other. The sealing performance of the storage jar is onlyrelated to the sealing ring 50 and is insusceptible to the opening andclosing of the structure. Moreover, the opening and closing of thestructure is not affected by the sealing ring 50, so that it is lessdifficult to open or close the storage jar. In addition, the sealingring 50 is sleeved on the outer side of the flange, and the sealing ring50 and the lid body 20 can be securely fixed without any glue, so thatthe storage jar is sanitary and environmentally friendly.

In some embodiments, the lid body 20 is provided with a first annulargroove, and the flange is arranged on an inner side of the first annulargroove. The first annular groove may have the same features as thesecond annular groove 23 or may be additionally arranged.

Similarly, the first annular groove increases the strength of the lidbody 20 which is therefore less susceptible to deformation duringassembly, so that it is ensured that the lid body 20 can tightly coverthe jar body 10.

In some embodiments, the jar body 10 is provided with an end surfaceabutting the lid body 20, and a sealing ring 50 is provided between theend surface and the lid body 20. The arrangement of the sealing ring 50on the end surface enables that the space of the accommodating cavity isnot occupied. In addition, it is convenient to replace the sealing ring,and suitable resilience of a sealing gasket further keeps the bucklingstructure 30 and the limiting structure 40 from loosening easily.

In some embodiments, the buckling structure 30 and/or the limitingstructure 40 is arranged at the first turnup 11, so that the formationof the accommodating cavity is not affected and the volume of theaccommodating cavity is not reduced. The first turnup 11 may furtherdeform to increase the elasticity of the buckling structure 30 and thelimiting structure 40, and the buckling structure 30 and the limitingstructure 40 are less susceptible to partial deformation and thus lesslikely to fracture. In addition, the entire storage jar has a simple andelegant appearance.

The buckling structure 30 and/or the limiting structure 40 beingarranged at the first turnup 11 means that the buckling structure 30 andlimiting structure 40 may be separately arranged on the first turnup 11or may be both arranged on the first turnup 11.

The foregoing embodiments are not limited to the technical solutions inthe embodiments, and the embodiments may be combined with each other toform a new embodiment. The foregoing embodiments are only intended todescribe the technical solutions of the disclosure rather than to limitthe technical solutions.
